FEEDING DEVICE FOR BUTTON-MACHINES, i800.

SPECIFICATION forming part of Letters Patent No. 535,996, dated March19, 1895.

Application filed October 9;].894- Serial No. 525,353. CN'o model.)

To a whom it may concern: Be it known that I, CHARLES RADCLIFFE, acitizen of the United States, residing at Newark, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Feeding Devices for Button or other Like Machines; and Ido hereby declare the following to be a full,clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

My present invention relates to improvements in devices forautomatically feeding the parts employed in the manufacture of buttons,or other small articles of a similar nature, to their proper positionson a piece of goods, previous to the forming of a complete button firmlyattached to the material.

The invention therefore consists in the con *struction of the variousparts of the mechan- .ism and the combination of the devices employed,in the manner herein explained, with a view to the productionof acheaper, a more convenient, and a practically efficient feeding device,for the purposes stated.

The devices to be hereinafter more fully explained and described areintended for use more especially in connection with the-button-attachingmachines, claimed by me in my previous Letters Patent, Nos. 486,895 and486,896, issued November 29, 1892; but the same may be used on any othermachine for feeding parts or buttons or small articles of a like nature.

The invention is illustrated in the accompanying sheets of drawings, inwhich- Figure 1 is a side View of a button-attaching machine, providedwith a feeding device embodying the principles of my invention. Fig. 2is a side view, on an enlarged scalejof my novel form offeeding device,and Fig. 3 is a top view of the same. Fig.4 is a view of the oppositeside of the feeding wheel used in connection with my improvement. Fig. 5is a perspective view, and Fig. 6 a face view of the receivingportions'of the Wheel illustrated in said Fig. 4.

As has been stated the main purpose of my present invention is toprovide an improved form of feeding device to be used in connection,more especially, with any construction of button machines, for feeding,either the back-plate with its post to be forced through the material,or the shell of the button, to that part of the machine, where saidparts are secured to the cloth and firmly fastened together to producethe finished button.

With this object in view, A, in the above described drawings, designatesany suitable stand or table provided with any form of operatingmechanism, such as for example, of the construction illustrated in myformer patent, No. 486,896. A is a standard secured in any convenientmanner upon said table or support, to which is secured, by means ofbolts or screws a, as indicated in dotted lines, in Fig. 1, or in anyother well-known manner, a half-section or shell (2. which is open onone end, as at a On a shaft 1), adapted to rofate in said shell issecured my novel form of back-plate or shell-feeding device 0, whichloosely fits in the contour of the open side a of said shell a, therebyvirtually closing said side, and while capable of a rotation therein,forms a pocket or hopper for the back-plates or shells of a button to befed by means of said wheel a intoa suitable chute or race-way d. Themechanism for producinga step-bystep'movement of the said wheel 0 issimilar to that described and illustrated in my previous patentsherein-above mentioned. The same consists essentially of a toothed wheela provided with a boss 6', and a screw e for securing the same to saidshaft 1). Arranged upon the table or support A is a tubular standard f,in which is adapted to move a post f, pivotally connected by means of arod f to the treadle of the machine. The upper end of said post f isprovided with a spring-actuated dog or jaw f which is in normal con tactwith the teeth a of the wheel 6, and when working the treadle, said postf moves upwardly, thereby causing the wheel 6 on the shaft 1) to moveone tooth and bringing a backplate or shell-receiving space 0' on thewheel 0, directly'in front of the receiving end d of the chute orrace-way d, to drop the backplate or shell into said chute. Of course itwill be evident, that this means for operating said wheel is but oneform of construction that may be used, and I may employ other forms forperforming the same result. The brushes b arranged on a sleeve b 611.said shaft, 1), for sweeping the back-plates or shells in saidreceiving portions 0 of the wheel 0, may be of a construction similar tothat described in my previous Letters Patent hereinabove mentioned, andmaybe operatedin a like manner, and it will therefore not be necessaryto further describe these parts.

As will be seen more especially from Figs. 4, 5 and 6, the shell orback-platefeeding wheel 0 is provided in its periphery with. a series ofretaining portions 0'. These consist essentially of a deep recess 0 ofanysuitable depth or width to receive the post on said back-plate of thehub on the shell of=the,button and the recessed guide-portions.-cdirectly back of theinclined faces c of saidn'eceivinm portions, toreceive thetedges of ttherbackplate, as will beseen fromaniusp-ect-iontof Fig. 5. Said recessed-portions are all angularlyarranged with the flat sides of .said wheeL and to retain the back-plateor shell in its receiving-portion, during therotation of said wheel 0 inthe direction. of the arrow .00, see Fig; ,2, the opposite side ofthelower portion of said Wheel is protected bya plate 9 secured to the;shell or by meansof screws 9'. Said pl-ate terminates directly beneaththereceivingpon tion d'of;thc chute- 0?. As will be noticedi from saidFigs. 5 andttl, the;recessedpartin of theireceiving portion 0' ofthewheel c, is. providedwith an inclined edge 0 thereby. considerablyenlarging ,the openingsof said recess 0 asrit comes in position in frontof. the receiving ,portion (1 of=thechute d and,

thereby enabling thetqlllek dischargeiofsaid back-plate on the shell ofa buttonrinito thei chute. Owing. to the inclination of the periphcraledge ofrsaid wvheel 0 coming in consi tact with said plate g, theback-plates or shells 1.

shellfeeding wheel arranged on said shaft,

of thebuttons will ireadily; place themselves in theproper posit-ions inthe receiving por tionsof said wheel.

The feedlng wheeh as. will be seen from. Fig.4, is made. intherman-ner-of-a toothedt wheel, having recessed parts a intowhich .thev

posts on the back-plates or the hubs ofthe;

shells arrange themselves .and are properly fed to the delivery chute,the.onl=y changein the construction of the wheels intended: for thefeeding of difierentparts OfvbllililOllS, .being in the differences inthe width anddepth of thesaid recessed portions 0 Otherwise theconstruction of the: wheels isalike; in. all respects. Owingtothearrangement and-.construction ofmthe receiving-portions .in said wheels,when a back-plate or shell endeavors to enter therecess in=a wrongpositiomit cannot be held in position thereimbei ng rejected and itsplace im mediately occupiedby another back-plate or shell, as thecasemay. be.

It'will be understood, that the receiving portion d of the chute (1,maybe in commu-ci nication with thewheel c at any suitable point, eitherat the. top, or atthe bottom or at any other point of the wheel, butpreferably attheside, as shown in the accompanying drawings.

The receiving portions in the wheel 0 may be of other suitableconfigurations than those shown herein, to suit the shape of the articleto be fed to other parts of the machine, the essential feature ofmymachinebeing a feeding wheel having an inclined peripheral surfacewithreceiving-portions in said inclined surface of any desirable shape.

Having thus described my invention, what I claim is-.

1. In a button attaching or other like machine, the herein describedfeeding device consisting essentially of a wheel, as 0, having receivingportions in its periphery, comprising therein recessed partsic recessedguide portionsc andan inclinededgeyc connected with one ofsaidaportions,substautiallyas and for the purposes set fOlhlL:
